6. Adjust the tension of the cross slide gib screws by cranking the cross slide leadscrew to move the
cross slide along the dovetail of the base. When the slide is centered over a gib screw, tighten
that screw until there is noticeable drag on the slide. Unscrew the setscrew slightly. Repeat until
all gib screws are adjusted.
7. Adjust the tension of the top slide gib screws by cranking the top slide leadscrew to move the top
slide along the dovetail of the cross slide. When the slide is centered over a gib screw, tighten
that screw until there is noticeable drag on the slide. Unscrew the setscrew slightly. Repeat until
all gib screws are adjusted.
Stub end mounting
The Climax KM4000 key mill can be mounted to stub ends as short as 8" (200 mm).
1. Turn the cutter end of the key mill toward the middle of the shaft.
2. Position the machine so that both chains are on the shaft and can be tightened.
3. Set up the machine as described in Steps #2 through #7 in “Standard shaft mounting”.
Large shaft mounting
Using the optional chain clamp assembly, shafts up to 24" (609 mm) in diameter can be machined.
Small shaft mounting
When mounting the KM4000 to shafts less than 7" (178 mm) diameter, an optional shim kit is
recommended. Shims are mounted to the base throat with flat-headed cap screws. The shim kit
enables the key mill to be mounted to shafts with diameters as small as 4" (100 mm).
If the shaft is disassembled, the key mill may be bench mounted and the shaft clamped to the
machine.
Extra long shaft mounting
If the shaft is long enough, V-blocks can be used to secure the shaft. A chain wrench or C-clamp may
be used to hold the shaft and V-blocks together. Setup and operation of the key mill is the same as
for standard shafts.
Bench Vise Mounting
The key mill mounted in a bench vise can be used as a stationary milling machine for small parts.
Typical applications include:

Slotting angle iron

Slotting tubes

Notching spanner nuts

Slotting gear pullers
